Answer:
7.7
Step-by-step explanation:
a ^2+b^2=c^2−2bccosA
l^2 = 5.9^2+7.1^2-2(5.9)(7.1)cos 72
Answer:
3/7
Step-by-step explanation:
Let's solve your equation step-by-step.
2(5x+3)=3x+9
Step 1: Simplify both sides of the equation.
2(5x+3)=3x+9
(2)(5x)+(2)(3)=3x+9(Distribute)
10x+6=3x+9
Step 2: Subtract 3x from both sides.
10x+6−3x=3x+9−3x
7x+6=9
Step 3: Subtract 6 from both sides.
7x+6−6=9−6
7x=3
Step 4: Divide both sides by 7.
7x

Hope it helps :)
You would transform 5x + 2x into the same term with the associative property, adding like terms. If you subsitute the different values into the expressions you notice that both have a rate of change of 7 like an arithmetic sequence. To see if any value will make the two expressions equal you make them equal to each other.
5x + 2x = 7x -1
7x = 7x - 1
0 = -1
No they will never have be a solution to both expressions to make them equal because they're parallel to each other.
They are equal to each other
